Volvo has developed an all-new direct injection technology called i-ART that will help make its new diesel engines more fuel-efficient. The launch is scheduled for this fall.
By featuring pressure feedback from each fuel injector instead of using a traditional single pressure sensor in the common rail, i-ART makes it possible to continuously monitor and adapt fuel injection per combustion in each of the four cylinders.
“Each injector has a small computer on top, which monitors injection pressure,” says Derek Crabb, Vice President of Powertrain Engineering at Volvo Car Group. “Using this information, the self-adapting i-ART system makes sure that the ideal amount of fuel is injected during each combustion cycle.”
According to Volvo, the combination of higher injection pressure and i-ART technology gives the customer an engine with improved fuel economy, considerably lower emissions, and high performance output.
The new diesel engines will be built in Skövde, Sweden, and mated to a new 8-speed automatic gearbox that contributes to a refined drive and excellent fuel economy.
